This specification covers nonreinforced concrete pipe intended to be used for the conveyance of sewage, industrial wastes, storm water, and for the construction of culverts. Pipe manufactured according to this specification shall be of three classes of nonreinforced concrete pipe identified as Class 1, Class 2, and Class 3. These pipes shall conform to the strength requirements given in this specification. The acceptability of the pipe shall be determined by the results of the following tests: strength test; absorption test; permeability test; and hydrostatic test. Concrete design shall conform to the physical and dimensional requirements for minimum wall thickness, and minimum three-edge bearing strength. The concrete shall consist of cementitious materials, mineral aggregates, and water. The aggregates shall be sized, graded, proportioned, and mixed with such proportions of cementitious materials and water as will produce a homogeneous concrete mixture of such quality that the pipe will conform to the test and design requirements of this specification. Pipe shall be subjected to either steam curing, water curing, or membrane curing. Special shapes or fittings such as wyes, tees, bends, and adapters for use with concrete pipe conforming to this specification shall conform to the applicable requirements for concrete pipe of corresponding class and internal diameter. Joints shall be compatible with those used in adjoining concrete pipes. Fabricated branches for wyes and tees shall be securely attached to the wall of the pipe in such a manner as not to restrict or otherwise interfere with the flow characteristics of the pipe.

This abstract is a brief summary of the referenced standard.

1. Scope

1.1 This covers nonreinforced concrete pipe intended to be used for the conveyance of sewage, industrial wastes, storm water, and for the construction of culverts.

1.2 A complete metric companion to Specification C14 has been developedC14M; therefore, no metric equivalents are presented in this specification.

Note 1—This specification is a manufacturing and purchase specification only and does not include requirements for bedding, backfill, or the relationship between field load conditions and the strength classification of pipe. However, experience has shown that the successful performance of this product depends upon the proper selection of the class of pipe, type of bedding and backfill, and care that the installation conforms to the construction specifications. The owner is cautioned that he must correlate the field requirements with the class of pipe specified and provide for or require inspection at the construction site.

The River Ritec flows towards Tenby, where it discharges via a 780 metre culvert/outfall system that passes beneath a railway embankment and sand dunes to discharge into the sea below typical low tide level. There is a history of flooding upstream of the culvert which imposes a restriction on the discharge of flows from the river catchment area during high river flow events. This is particularly true when high river flows coincide with high astronomic tide levels.

Levee analysis is becoming an increasingly important topic as the infrastructure ages. Many sections are in need of re-engineering improvements as consideration is given to their replacement. Concepts utilized in their original design are being re-examined. Many of these structures were designed 20 to 50 years ago, and the tools utilized in such analysis have changed significantly. Our understanding of the processes involved has also improved with time.
Levee structures are typically three-dimensional in character...
